Question

trees = ['coconut', 'sequoia', 'weeping', '23', '24', '25', 200, '26', '27', '28', 300, 'T']

I need a python code that either prints out only certain elements of a list, or appends certain item of a list to a new list then prints out that new list.

For example:

trees = ['coconut', 'sequoia', 'weeping', 300, 'T'] or

trees2 = []

trees2 = ['coconut', 'sequoia', 'weeping', 300, 'T']

Answer 1

trees = ['coconut', 'sequoia', 'weeping', '23', '24', '25', 200, '26', '27', '28', 300, 'T']

trees2 = []  # create an empty list
for i in range(len(trees)):  # go through all items in trees
    if i < 3 or i >= 10:  # if a certain condition is true
        trees2.append(trees[i])  # then add item to new list
print(trees2)  # print the new list

# we can do exact thing with slicing as well..
trees2 = trees[:3] + trees[10:]
print(trees2)

'['coconut', 'sequoia', 'weeping', 300, 'T'] ['coconut', 'sequoia', 'weeping', 300, 'T'] Process finished with exit code o
